What size is the AFS cache on the debian server?  Is the AFS volume you are
storing into hosted on the the debian server?

I suspect the scp process on windows box is timing out while waiting for the 
AFS client on debian box to write the full AFS cache to AFS server.

I do not know if winscp allows for much debug messages.  Does the problem 
occur if after scp'ing to a local disk on debian, you scp the file from
the local disk on debian box to the AFS home dir on debian box (e.g. scp
from debian box to itself)?  If so, you might want to scp with a lot of 
debug flags to see what the scp client says.
